如何在MVC4中将Json字符串转换为C#对象 [英] How to Convert Json string into C# object in MVC4

问题描述

我有一个使用Model字符串值属性在控制器上提交的json字符串.我想将此json字符串转换为c#通用列表对象.

I have a json string which is submitted on controller using Model string value property. I want to convert this json string into c# generic list object.

下面是我的json字符串

Below is my json string

{
    "MLIDandRackPosition": [
        {
            "MLID": "27",
            "PositionInRack": "3"
        },
        {
            "MLID": "24",
            "PositionInRack": "4"
        }
    ]
}

下面是我的课程

  public class MLIDandRackPosition
    {
        public int MLID { get; set; }
        public int PositionInRack { get; set; }
    }

我想要控制器动作方法上json字符串中的MLIDandRackPosition类的列表.

I want a List of MLIDandRackPosition class from json string on controller action method.

请帮助

推荐答案

您的对象将正确绑定到

public ActionResult SomeAction(IEnumerable<MLIDandRackPosition> MLIDandRackPosition)

如果设置以下ajax参数

If you set the following ajax parameters

var data = { "MLIDandRackPosition": [ { "MLID": "27", "PositionInRack": "3" }, { "MLID": "24", "PositionInRack": "4" } ] };

$.ajax({
  ...
  traditional: true,
  contentType: "application/json; charset=utf-8",
  data: JSON.stringify(data)
})

尽管我建议更改参数名称(例如model)和var data = { "model": [ { "MLID": ....] };

although I would recommend changing the parameter name (to say model) and var data = { "model": [ { "MLID": ....] };
